WebCorrect option is A) The excretory organs of flatworms (Platyhelminthes) are flame cells and function like a kidney, removing waste materials. Nephridia remove metabolic wastes from an animal's body. They are present in annelids.

WebWater BalanceBecause Dugesia’s body cells contain more solutes than fresh water does, water continually enters its body by osmosis. Excess water moves into a network of tiny tubules that run the length of Dugesia’s body. Side branches are lined with many flame cells, specialized cells with beating tufts of cilia that resemble a candle flame.

WebExcretion and osmoregulation by flatworms is controlled by "flame cells" located in protonephridia (these are absent in some forms). Flatworms lack a respiratory or circulatory system; these functions take place by absorption through the body wall. Nonparasitic forms have a simple, incomplete gut; even this is lacking in many parasitic species. WebPlanaria are flatworms that live in fresh water.

WebStructure and Function of Flatworms. Flatworms range in length from about 1 millimeter (0.04 inches) to more than 20 meters (66 feet). They have a flat body because they do not have a coelom or even a pseudocoelom. They also lack a respiratory system. Instead, their cells exchange gases by diffusion directly with the environment. WebFlatworms are more complex than cnidarians. Cnidarians have two layers of cells, the ectoderm and the endoderm; flatworms have a middle layer called the mesoderm between the other two layers (Fig. 3.16). This extra layer is important because its cells specialize into a muscular system that enables an animal to move around.
